WIN-8A Low Background αβ Meter (independent Injection)

(92) Reviews

Product Description:

WIN-8A independent injection low background αβ measuring device has a variety of 2 to 12 specifications, using a new appearance design, can be equipped with a tablet computer, to achieve remote control. Each channel of the instrument can be measured separately separately, measured separately and produced separately; all the parameters of the instrument are automatically set by the software program, and the measurement process is highly automated. The weak radioactivity of the sample measured by this instrument requires no consumables, the experimental cost is low, and the operation is easy. It is the first choice for measuring the total αβ specific activity of the sample. It is mainly used for measuring the total α and β activity concentration in samples in the fields of radioactive detection, radiation environment monitoring, nuclear power plant, geological exploration, colleges and universities, entry-exit inspection and quarantine, third-party testing and scientific research institutions.
